CROSS REFERENCE TO RELATED APPLICATION

The present application claims priority to Korean Patent Application No. 10-2022-0015262, filed Feb. 7, 2022, the entire contents of which is incorporated herein for all purposes by this reference.

BACKGROUND OF THE INVENTION Field of the Invention

The present disclosure relates to a stamp type fluid delivery container with microneedles, the container being used to inject fluid for skin or scalp care, treatment, etc. while it is tapped on the skin or scalp. In more particularly, the present disclosure relates to a stamp type fluid delivery container with microneedles, the container having a simple structure without a specific nozzle opening/closing structure and being used to uniformly and smoothly supply fluid to the microneedles.

Description of the Related Art

In general, fluid that is used for skin or scalp care, treatment, etc. is directly supplied to the skin or the scalp, but there is a problem that it is difficult to expect a great effect because the fluid spreads on the skin or the outer layer of the scalp.

In order to solve this problem, several types of fluid delivery containers that make fluid permeate even into a dermis (inner skin) other than the outer layer of a skin or a scalp using microneedles have been proposed.

For example, according to Korean Patent No. 10-1993706, a connecting housing is coupled to the upper portion of a containing member (container) keeping fluid, a needle housing having microneedles inserted in slots formed in parallel is coupled to the connecting housing, and a cover bar and a nozzle bar are inserted in a nozzle hole at the center of the connecting housing to be able to be elastically moved up and down, so when the nozzle bar is pressed on the skin or the scalp, the nozzle hole is opened, and fluid is supplied through a medical fluid, the connecting housing, or the microneedles in the slots of the needle housing to permeate into the dermis (inner skin) of the skin or the scalp.

However, according to the fluid delivery container, the nozzle opening/closing structure and the connecting housing are separately formed, so the structure is complicated, and the fluid supplied through the nozzle hole of the connecting housing is supplied to the entire needle housing through the front space of the connecting housing rather than being directly supplied to the slots of the needle housing, so there is a problem that fluid is not uniformly and smoothly supplied to the slots of the needle housing.

Further, according to Korean Patent No. 10-1776154, a base is coupled to an upper portion of a containing member (container) without a nozzle structure, a cover microneedles inserted in slots famed in parallel is coupled to the base, and a sponge member is coupled to an upper portion of the cover such that fluid permeates into the dermis (inner skin) of the skin or the scalp through the microneedles without a nozzle opening/closing structure.

However, according to this fluid delivery container, there is no nozzle opening/closing structure, but a specific member such as the base is further coupled, so the structure is complicated. Further, the fluid in the containing member is directly supplied to a fluid channel hole famed separately from the slots of the cover, so there is a problem that fluid is smoothly supplied, but the fluid is not supplied by an appropriate amount and is excessively supplied.

Further, there is another problem that since the fluid channel hole of the cover keeps open even when the fluid delivery container is kept or carried, fluid flows and leaks outside.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

A stamp type fluid delivery container with microneedles of the present disclosure, as shown in FIGS. 1 to 6 , includes a container body 10, a needle housing 20, a sealing cover 30, and a closing cap 40.

The container body 10 keeps fluid in the internal space thereof and has a threaded coupling portion 11 on the outer side of the upper portion and a coupling groove 12 inside the upper portion.

The coupling groove 12 may be stepped up and down and may be formed in a rectangular shape when seen from above.

The needle housing 20 has a rectangular body 21 corresponding to the coupling groove 12 of the container body and is fixed and coupled by being forcibly inserted in the coupling groove. Further, the needle housing 20 has an up-down stepped structure, which corresponds to the up-down step of the coupling groove, on the outer side.

Slots 22 are vertically foiled and arranged to the left and right in parallel in the needle housing 20 and plate-shaped microneedles 25 are inserted in the slots, respectively.

Sub-microneedles 25 a protruding from the upper end of each of the microneedles 25 protrude upward out of the needle housing, the slots 22 of the needle housing are tapered such that the width increases downward, and holding steps 25 b famed on both sides of the lower portion of the microneedles are retained in the slots 22. Accordingly, the microneedles are not separated upward out of the slots 22 and fluid is smoothly supplied to the slots 22.

The sealing cover 30 is made of rubber and is installed to cover the entire upper portion of the coupling portion 11 of the container body, thereby preventing fluid flowing out through the slots 22 of the needle housing from leaking to the outside. A needle seat groove 32 in which the sub-microneedles 25 a at the upper ends of the microneedles 25 are inserted is famed at the center portion of the bottom of the sealing cover.

The closing cap 40 is thread-fastened to the coupling portion 11 of the container body and presses the sealing cover 30 so that the sealing cover is operated for sealing.

In particular, a fluid discharge hole 13 is foiled in an oblong shape on the bottom of the coupling groove 12 of the container body to cross the slots 22 of the needle housing and an air hole 14 is formed in the upper portion of the coupling portion 11 so that air can flow while the fluid in the container body is prevented from leaking. Accordingly, fluid is smoothly supplied to the microneedles 25 by a simple structure without a separate nozzle opening/closing structure.

The fluid discharge hole 13 is not formed through the bottom of the coupling groove 12 of the container body and is formed in an oblong shape, thereby preventing excessive supply of fluid. Further, the fluid discharge hole 13 is famed across the slots 22 of the needle housing so that fluid is uniformly supplied to the slots of the needle housing.

A bottom cap 15 made of rubber is coupled to the bottom of the container body 10 by forcible-fitting to be able to be open and closed for back-filling of fluid.

Though not stated about, reference numeral ‘10 a’ indicates the internal space of the container body and reference numeral ‘15 a’ indicates a stepped groove famed at a lower portion of the container body to couple the bottom cap.

The operation and function of the present disclosure having the configuration described above are described hereafter.

First, a process of assembling the fluid delivery container of the present disclosure is described. The plate-shaped microneedles 25 are inserted into the slots 22 famed to the left and right in parallel in the needle housing 20 from the bottoms of the slots 22 and the needle housing 20 is inserted into the coupling groove 12 formed inside the upper portion of the container body 10.

Since the oblong fluid discharge hole 13 is formed on the bottom of the coupling groove 12 of the container body, the slots 22 of the needle housing 20 are positioned across the fluid discharge hole 13.

In this state, the sealing cover 30 is installed on the top of the container body without interfering with the sub-microneedles 25 a at the upper ends of the microneedles because the needle seat groove 32 is famed at the center portion of the bottom of the sealing cover.

Then, the closing cap 40 is coupled to the coupling portion 11 on the outer side of the upper portion of the container body.

In this state, the bottom cap 15 coupled to the bottom of the container body is separated, the container body 10 is filled with fluid from the back, and then the bottom cap 15 is coupled back for closing.

Since the sealing cover 30 is coupled to the upper portion of the container body 10 assembled in this way in the present disclosure, fluid in the container body 10 is prevented from leaking to the outside.

In order to use the fluid delivery container of the present disclosure, a user separates the closing cap 40 from the upper portion of the container body 10 and separates also the sealing cover 30 at the upper portion of the container body, and then the user can use the fluid delivery container.

In this prepared state, the user taps the sub-microneedles 25 a of the microneedles coupled to the upper portion of the container body 10 on a scalp, a skin, etc., whereby the fluid in the container body is supplied to the microneedles and injected into micro holes formed by the sub-microneedles 25 a.

Describing this process in more detail, when the fluid in the container body 10 is supplied through the fluid discharge hole 13 famed in an oblong shape on the bottom of the coupling groove 12, the fluid is supplied also to the slots 22 of the needle housing which are famed in parallel across the fluid discharge hole 13.

In particular, since the fluid discharge hole 13 is not famed through the bottom of the coupling groove 12 of the container body and is formed in an oblong shape, excessive supply of fluid is prevented. Further, since the fluid discharge hole 13 is famed across the slots 22 of the needle housing, fluid is uniformly supplied to the slots of the needle housing.

Further, since the air hole 14 is famed in the upper portion of the container body 10, external air flows into the container body and enables the fluid in the container body to be smoothly discharged through the fluid discharge hole 13 without leakage of the fluid.

As described above, an appropriate amount of fluid is uniformly supplied to the slots 22 of the needle housing through the fluid discharge hole 13 of the container body and is injected through the microneedles 25 coupled in the slots 22.

Therefore, according to the present disclosure, since the needle housing 20 having the microneedles 25 is coupled to the coupling groove 12 at the upper portion of the container body 10, the fluid discharge hole 13 is famed in an oblong shape on the bottom of the coupling groove 12 across the slots 22 of the needle housing, and the air hole 14 through which air can flow without leakage of fluid is foiled in the upper portion of the container body, it is possible to uniformly and smoothly supply fluid not excessively, but appropriately to the microneedles even without a nozzle opening/closing structure and it is also possible to use the fluid delivery container without the possibility of leakage of fluid at normal times.
